Can't turn off tooltips in window list

[jhalpin100]

I keep getting tooltips in the window list widget, and can't turn them
off. I've used dconf-editor to turn off every entry it has for
tooltips, but I still see them for the window list.

When I say "window list" I'm referring to the item in the "Add to
Panel" dialog.

In dconf-editor, the org->mate->panel->general entry shows tooltips-
enabled = false. Is there a problem with dconf-editor? Maybe it's not
communicating the setting to the underlying system or something?

Thanks

Joe

Is there a problem with dconf-editor?

No. The gsettings key seems to be used only by very few panel applets (e.g. menu). The window list is based on libwnck's tasklist which doesn't support disabling tooltips.

May I please ask for this issue to be reopened. It is still true that there is no obvious way to disable these tooltips but it can be done.
Please look at Linux Mint Debian Edition 3 or 4, these use mate panel with cinnamon, the window list, and nemo-preview, and the libwnck tooltips do not appear.
If nemo-preview is used with mate-desktop, the tooltips clash with the nemo-preview.

The tooltips do not pay any heed to the desktop theme, and are starting to look dated. May I suggest having a 'disable windowlist tooltips' tickbox option in the mate-panel configuration dialog?

This issue still is open.
I do not know cinnamon well, but I think they use their own panel: https://github.com/linuxmint/cinnamon/blob/master/js/ui/panel.js
I remember looking in the code of libwnck to make a disable tooltip setting, but I found it very complicated to get it working reliably.

This is part of libwnck.
A while ago i use this patch for personal use which disables tooltips.

So this is not directly in our hand.
In theory libwnck needs a function to enable/disable tooltips which we can call from mate-panel code.
Or a gsettings key in libwnck itself.
But i can't do that.

I would love to use this 'patch' but I have no idea where to put it or what to do with it.

As said countless times here, it is part of libwnck.

[minuxlintebiandedition]

I assume you mean adding that text to the source code and compiling it?

Or putting it in some config file?

[lukefromdc]

That is c code to be patched into a source code file and built

[minuxlintebiandedition]

I have never compiled anything in my life.

Ok

[linuxCowboy]

This long-standing issue has been annoying me, too.

The culprit is the libwnck library.

Window Navigator Construction Kit

Get the source in your distro

# debian
apt-get source libwnck3

patch tasklist.c

sed -i '/gtk_widget_set_tooltip_text/ s/ text/ NULL/' libwnck/tasklist.c

compile, copy to libdir and replace the link

e.g.
sudo ln -sf libwnck-3.so.0.3.0.fix libwnck-3.so.0

and the tooltips are gone for good!

You can test with

./test-tasklist

and find the exact library name with

ldd /usr/lib/mate-panel/wnck-applet |grep wnck
or
ldd test-tasklist |grep wnck

[raveit65]

Hmm, i just tested
https://gitlab.gnome.org/GNOME/libwnck/-/commit/6aa863b5825dd9dfbdbb0e60f52c598f1ba959e8
and
https://gitlab.gnome.org/GNOME/libwnck/-/commit/c55f49e18710e5d26cf5cc7301b140d1dc73b7c0
But it doesn't work very well. With most windows the tooltip are there. eg.

Is there a work with mate-panel needed to see the option in panel settings?

[muktupavels]

Automatically are hidden only useless tooltips. To completely disable tooltips you have to use API - wnck_tasklist_set_tooltips_enabled.

[raveit65]

OK, got it
